Abstract: Hydrogen is regarded as a promising energy carrier to substitute fossil fuels. However, storing hydrogen with high density remains a challenge. NaBH 4 is a potential hydrogen storage material due to its high gravimetric hydrogen density (10.8 mass%), but the hydrogen kinetic and thermodynamic properties of NaBH 4 are poor against the application needs. Nanosizing is an effective strategy to improve the hydrogen properties of NaBH 4 . In this context, we report on the direct synthesis of NaBH 4 nanoparticles (~6–260 nm) from the NaOCH 3 precursor. The hydrogen desorption properties of such nanoparticles are reported as well as experimental conditions that lead to the synthesis of (Na 2 B 12 H 12 ) free NaBH 4 nanoparticles.
